Ok Guys I know I have been asking a lot of weird questions but here is one that is different. I am looking at running smaller tires than stock. With the type of racing I am doing I need tires that resemble flat track tires. Hoosier or American racer do not make them in 12" I have seen the Duro tires but most I have seen are 6 ply and that is to stiff of a sidewall. I did find some tires that are 23 X 10- 12 and are 4ply. They have a descent tread and less side knob. My question is will running these tires harm the diff's or trans since they are shorter and all 4 are the same size width wise? I wont likely run in AWD but just not sure about it?
